Serial No. 654,170.

To all whom it may concern:

Be it known that 1, ROBERT DEHRENBAOH, citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Non-Relillable Bottles, of which the followingis a specification.

This invention relates to non-refillable bottles, and one aim of theinvention is to provide a bottle of this type which, while simple inconstruction, and consisting of but few parts, cannot be refilled afterhaving been once emptied, the use of the bottle after having been onceemptied, in dispensingliquids of a quality inferior to its originalcontents, being in this manner prevented.

One aim of the invention is to provide a bottle of this type soconstructed that the liquid will flow freely therefrom when the bottleis tilted to discharge its contents, and from which the entire contentsmay be poured.

A further aim of the invention to so construct the bottle that liquidwill not accumulate in the neck thereof after the bottle has been tiltedto discharge part of its contents and returned to upright position.

The invention aims still further to provide against the insertion of awire or like implement into the neck of the bottle in such manner as tolift the valve of the bottle from its seat.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is avertical sectional view through a bottle constructed in accordance withthe present invention. Fig. 2 is a horizontal sectional view on the line2-2 of Fig. 1. Fig. 3 is a similar view on the line 3-3 of Fig. 1. Fig.i is a view in elevation of the valve casing of the bottle removed fromthe neck thereof. Fig. 5 is a view similar to Fig. 1, but showing thebottle tilted to discharge its contents.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

In the drawing, the bottle is indicated by the numeral 1 and the neckthereof by the numeral 2, the neck being bulged as shown at 3 and at itspoint of juncture with the body of the bottle being contracted as at lto form a shoulder 5.

For a purpose to be presently explained, the neck 2 of the bottle isformed intcriorly at its upper extremity with an annular groove 6.

A valve to be presently described is designed to prevent re-filling ofthe bottle after it has once been emptied of its contents and thecasingfor this valve is indicated by the numeral 7 and may be of glassor any other suitable material, it being substantially cylindrical andbeing" contracted at its lower end to form a neck 8. The casing at itsupper end has its wall considerably thickened to form a head 9 having adischarge opening 10 extending therethrough, and this head is furtherprovided with an outwardly projecting circumscribing flange 11. The head9 is formed with a circumscribing groove 12 and a spring split washer 13is fitted in the groove 12 and 6X pended into the groove 6 in the bottleneck, the valve casing being in this manner held within the neck afterits insertion thereinto. A washer 1a is preferably disposed between theflange 11 and the upper end of the neck 3 so as to prevent leakage ofthe liquid contents of the bottle around the said head 9. A packingwasher 15 of rubber or cork or some other suitable packing material isfitted upon the contracted lower end. of the valve casing 7 andSurrounds the neck 8, and when the valve casing is inserted into thebottle neck this packing washer will be compressed to a greater or lessextent be tween the wall of the neck 8 and the shouldcr 5 at the lowerend of the bottle neck 3. This washer 15 serves not only to space thelower end of the valve casing from the bottle neck and prevent its beingbroken by impact with the wall of the neck, should it be formed ofglass, but also serves to prevent liquid flowing into the body of thebottle, except through the neck of the valve casing. It will be observedfrom inspection of the several figures of the drawing that the valvecasing is of less diameter than the bottle neck, so that a considerablespace is afforded between the interior of the bulged portion of the neck3 to allow the liquid to more readily flow from the bottle.

As shown in F 1 and 5 of the drawings the valve chamber is formedinteriorly near its upper end with a partition 16 which serves to dividethe said neck into an upper chamber 17 and a lower chamber 18, the valveof the bottle being housed in this latter chamber, as will be presentlyexplained. By contracting the lower end of the chamber, a valve seat isformed, indicated by the numeral 18 and the wall of the chamber isformed with a series of openings 19 located immediately above this seat.The upper side of the packing washer 15 registers with the lower edgesof the openings 19 so that after the bottle has been tilted to dischargeits contents and is returned to upright position, any liquid which wouldotherwise accumulate in the neck 3 will be directed through the openings19 and into the bottle. Immediately below the plane of the partition 16,the wall of the valve chamber is formed with openings 20 and the saidwall of the casing is formed interiorly with ribs 21 which extend fromthe upper ends of the openings 19 to points adjacent the openings 20,these ribs being parallel to the aXis of the valve chamber. The valve isindicated by the numeral 22 and is substan tially of inverted conoidalform. This valve 22 is hollow, as shown in Figs. 1, 3 and 5. It isslidably received between the ribs 21, and normally rests upon the valveseat 18 and is guided in its sliding movement in the valve casing by theinner edges of the said ribs. A ball-weight 23 is loosely held with inthe valve 22 and assumes the position shown in Fig l of the drawing whenthe valve is in closed position. hen the bottle is tilted to dischargeits contents, the weight 23 will fall into what is normally the upperend of the valve and will assume about the position shown in Fig. 5.Thus, should the valve tend to adhere to its seat, the dropping of theweight into the upper end of the valve will serve to jar it from itsseat. To insure of proper seating of the valve when the bottle isrestored to upright position after having been tilted to pour liquidtherefrom there is provided a spring 24 secured at its lower end to theupper end of the valve 22 and at its upper end to a stud 25 which isintegral with the under side of the partition 16. This spring 24 iscomparatively weak, it being only sufficiently strong to slide the valvedownwardly to its seat when the bottle is in upright position.

It will be observed from inspection of Fig. 5 of the drawing, that whenthe bottle is tilted to discharge its contents the valve 22 will slidedownwardly between the ribs until its upper end contacts with the stud25. This will prevent the valve interfering with the free passage ofliquid through the openings 20.

The wall of the valve casing is formed, above the plane of the partition16 with a number of openings 26 which establish communication betweenthe chamber 17 and the space between the valve casing and the bulgedwall of the bottle neck.

It will be readily understood from the foregoing that when the bottle istilted, the ball-weight 23 falling into the upper end of the valve willserve to jar the valve loose from its seat, and the weight of the liquidflowing into the valve casing will cause the valve to slide down intoengagement with the stud 25. Liquid will then flow through the openings19 and into the space between the valve casing and the bulged wall ofthe bottle neck 3 and will also flow into the valve casing-between theribs 21 and the wall of the casing and the said valve and out throughthe openings 20 into the said space between the neck of the bottle andthe wall of the casing. From this space the liquid will flow through theopenings 26 into the chamber 17 and out through the discharge opening 10in the head of the easing. Air entering at the top of the opening 10will pass through the uppermost ones of the openings 26 and between theupper side of the valve casing and the upper side of the neck 3 andthrough the uppermost ones of the openings 19 and into the bottle.

The interiorly formed shoulder of the hollow valve 22 serves as atemporary stop for the ball weight 23 to retard its move ment from oneend of the valve to the other and therefore, the valve being normallyheld in closed position by the spring 2%, prevents the opening of thevalve until the bottle has been considerably tilted. As soon however, asthe ball passes this shoulder. it immediately falls to the outer end ofthe valve and moves the valve against the action of the spring to openthe same. Of course upon the closing of the valve, the ball weight doesnot interfere for as soon as it is moved from the outer end of the valvethe spring comes into play and the valve will be closed as soon as thebottle reaches a horizontal position.

From the foregoing it will be observed that the bottle is so constructedthat liquid may be freely poured therefrom and that air entering thebottle will not interfere with the valve nor With the outflowing liquid.

Having thus described the invention What is claimed as neW is Anon-refillable bottle having a valve seat, a hollow valve normallyresting upon the seat by one end and reduced intermediate its length byan interiorly formed inwardly directed encircling shoulder, a ballWeight loosely confined Within the valve and 10 movable from end lo endthereof over said shoulder, and a guard for the valve.

In testimony whereolt' I aiflix my signature in presence of twoWitnesses.
